Tapping device

Abstract

The invention provides a tapping device. The tapping device comprises a tapping machine, a detection mechanism and a feeding mechanism, wherein the tapping machine, the detection mechanism and the feeding mechanism are respectively connected with a control system; the tapping machine is arranged on one side of the feeding mechanism; the detection mechanism is arranged above the feeding mechanism;the detection mechanism is positioned in front of the tapping machine; the detection mechanism comprises a first sensor and a detection pin capable of moving up and down; diameter of the bottom of thedetection pin is smaller than or equal to that of the bottom hole of the workpiece to be tapped; the first sensor is used for detecting displacement of the detection pin; the bottom of the detectionpin extends into the bottom hole, if position of the bottom hole of the workpiece to be tapped is incorrect, the diameter of the bottom hole is too small or position of the workpiece to be tapped is incorrect, the bottom of the detection pin cannot extend into the bottom hole, and the first sensor can detect the displacement abnormality of the detection pin; a drill of the tapping machine can be prevented from processing a non-bottom hole position; service life of the tapping machine is prolonged; and tapping quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of thread tapping, in particular to a thread tapping device. Background technique [0002] For products that require tapping, a bottom hole must be drilled on the product, and then tapped by a tapping machine on the bottom hole. Existing tapping device all is to directly send the product of bottoming hole into tapping machine and carry out tapping. However, the position of the bottom hole on the product cannot be guaranteed to be correct. Incorrect position of the bottom hole will lead to inaccurate tapping, and the drill bit of the tapping machine will process the position of the product without the bottom hole, which may easily cause the drill bit to be damaged. Damage will affect the service life of the tapping machine. Moreover, the position of the bottom hole on the product is more difficult to detect with the naked eye. If the detection is performed manually, there will be errors in the detection res...

Problems solved by technology

However, the position of the bottom hole on the product cannot be guaranteed to be correct. Incorrect position of the bottom hole will lead to inaccurate tapping, and the drill bit of the tapping machine will process the position of the product without the bottom hole, which may easily cause the drill bit to be damaged. Damage, affecting the service life of the tapping machine

Moreover, the position of the bottom hole on the product is difficult to detect with the naked eye. If the detection is performed manually, there will be errors in the detection results, and it will take too long, which will affect the production efficiency.
